In 3118 Clan Wolf launched a probing attack on Harvest, only to be repelled by the Twenty-First; however, whilst the Twenty-First successfully rebuffed the Wolf attack, they used the new HippogriffProtoMechs they had obtained from Clan Snow Raven poorly, and the resulting poor performance of the Hippogriff led to it being redeployed to solahma units after the battle.[3]
